Seiurus Aurocapilla Nest Maine 1
The ovenbird (''Seiurus aurocapilla'') is a small songbird of the New World warbler family (Parulidae). This migratory bird breeds in eastern North America and winters in Central America, many Caribbean islands, Florida and northern Venezuela. Taxonomy The genus ''Seiurus'' is currently treated as monotypic, containing only the ovenbird; it is genetically distinct from all other species in the family Parulidae, probably the first genus to evolve separately from the rest of the family. Before the recent genetic studies were carried out, the waterthrushes were also included in ''Seiurus''; these are now treated separately in the genus ''Parkesia'' as they are not very closely related to the ovenbird. The species name ''aurocapilla'' is a noun phrase, so the original spelling is retained, not changed according to the gender of the genus name; Linnaeus originally named it ''Motacilla aurocapilla'', and the ending is not changed to -''us'' as commonly cited in the past.

William John Swainson
William John Swainson FLS, FRS (8 October 1789 – 6 December 1855), was an English ornithologist, malacologist, conchologist, entomologist and artist. Life Swainson was born in Dover Place, St Mary Newington, London, the eldest son of John Timothy Swainson the Second (1756–1824), an original fellow of the Linnean Society. He was cousin of the amateur botanist Isaac Swainson.Etymologisches Worterbuch der botanischen Pflanzennamen by H. Genaust. Review by Paul A. Fryxell ''Taxon'', Vol. 38(2), 245–246 (1989). His father's family originated in Lancashire, and both grandfather and father held high posts in Her Majesty's Customs, the father becoming Collector at Liverpool. William, whose formal education was curtailed because of an impediment in his speech, joined the Liverpool Customs as a junior clerk at the age of 14."William Swainson F.R.S, F.L.S., Naturalist and Artist: Diaries 1808–1838: Sicily, Malta, Greece, Italy and Brazil."

Skylark
''Alauda'' is a genus of larks found across much of Europe, Asia and in the mountains of north Africa, and one of the species (the Raso lark) endemic to the islet of Raso in the Cape Verde Islands. Further, at least two additional species are known from the fossil record. The current genus name is from Latin ''alauda'', "lark". Pliny the Elder thought the word was originally of Celtic origin. Taxonomy and systematics The genus ''Alauda'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. The type species was subsequently designated as the Eurasian skylark. The genus ''Alauda'' has four extant and at least two extinct species. Formerly, many other species have also been considered to belong to the genus. Extant species The genus contains four species: Extinct species * †''Alauda xerarvensis'' (late Pliocene of Varshets, Bulgaria) * †''Alauda tivadari'' (late Miocene of Polgardi, Hungary) Former species Previ ...

Wing Covert
A covert feather or tectrix on a bird is one of a set of feathers, called coverts (or ''tectrices''), which, as the name implies, cover other feathers. The coverts help to smooth airflow over the wings and tail. Ear coverts The ear coverts are small feathers behind the bird's eye which cover the ear opening (the ear of a bird has no external features) Tail coverts The uppertail and undertail coverts cover the base of the tail feathers above and below. Sometimes these coverts are more specialised. The "tail" of a peacock is made of very elongated uppertail coverts. Wing coverts The upperwing coverts fall into two groups: those on the inner wing, which overlay the secondary flight feathers, known as the secondary coverts, and those on the outerwing, which overlay the primary flight feathers, the primary coverts. Within each group, the feathers form a number of rows. The feathers of the outermost, largest, row are termed greater (primary-/secondary-) coverts; those in the next row ...

Buff (color)
Buff (latin ''bubalinus'') is a light brownish yellow, ochreous colour, typical of buff leather. Buff is a mixture of yellow ochre and white: two parts of white lead and one part of yellow ochre produces a good buff, or white lead may be tinted with French ochre alone. As an RYB quaternary colour, it is the colour produced by an equal mix of the tertiary colours citron and russet. Etymology The first recorded use of the word ''buff'' to describe a colour was in ''The London Gazette'' of 1686, describing a uniform to be "...a Red Coat with a Buff-colour'd lining". It referred to the colour of undyed buffalo leather, such as soldiers wore as some protection: an eyewitness to the death in the Battle of Edgehill (1642) of Sir Edmund Verney noted "he would neither put on arms rmouror buff coat the day of the battle". Such buff leather was suitable for ''buffing'' or serving as a ''buffer'' between polished objects. It is not clear which bovine "''buffalo''" referred t ...

Remiges
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices (), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on them. Even flightless birds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tawny (color)
Tawny (also called tenné) is a light brown to brownish-orange color. Etymology The word means "tan-colored", from Anglo-Norman ''tauné'' "associated with the brownish-yellow of tanned leather", from Old French ''tané'' "to tan hides", from Medieval Latin ''tannare'', from ''tannum'' "crushed oak bark", used in tanning leather, probably from a Celtic source (e.g. Breton ''tann'', "oak tree"). Electronic definitions of tawny A digitized version of the 1912 book ''Color Standards And Color Nomenclature'' lists tawny as AE6938, tawny-olive as 826644 or 967117, ochraceous-tawny as BE8A3D or 996515, and vinaceous-tawny as B4745E. HP Labs' ''Online Color Thesaurus'', which lists colors found through their ''Color Naming Experiment'', gives tawny as CC7F3B, noting it is "rarely used", and lists its synonyms as: light chocolate, caramel, light brown, and camel. Dictionary of Color lists tawny as AE6938 or A67B5B, and tawny birch as A87C6D, A67B5B or 958070. It also lists "lion t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms ''beak'' and ''rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections – the upper and lower mandibles – are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the word "beak" was, in the past, generally restricted to the sharpened bills o ...

Tarsus (skeleton)
In the human body, the tarsus is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot (Cuboid bone, cuboid, medial, intermediate, and lateral cuneiform bone, cuneiform, and navicular) and hindfoot (Talus bone, talus and calcaneus). The tarsus articulates with the bones of the metatarsus, which in turn articulate with the proximal phalanges of the toes. The joint between the tibia and fibula above and the tarsus below is referred to as the ankle, ankle joint proper. In humans the largest bone in the tarsus is the calcaneus, which is the weight-bearing bone within the heel of the foot. Human anatomy Bones The talus bone or ankle bone is connected superiorly to the two bones of the lower leg, the tibia and fibula, to form the ankle, ankle joint or talocrural joint; inferiorly, at the subtalar joint, to the calcaneus or heel bone. Together, the talus and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tail
The tail is the section at the rear end of certain kinds of animals’ bodies; in general, the term refers to a distinct, flexible appendage to the torso. It is the part of the body that corresponds roughly to the sacrum and coccyx in mammals, reptiles, and birds. While tails are primarily a feature of vertebrates, some invertebrates including scorpions and springtails, as well as snails and slugs, have tail-like appendages that are sometimes referred to as tails. Tailed objects are sometimes referred to as "caudate" and the part of the body associated with or proximal to the tail are given the adjective "caudal". Function Animal tails are used in a variety of ways. They provide a source of locomotion for fish and some other forms of marine life. Many land animals use their tails to brush away flies and other biting insects. Most canines use their tails to comunicate mood and intention . Some species, including cats and kangaroos, use their tails for balance; and some, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing Chord (biology)
Wing chord is an anatomical measurement of a bird's wing. The measurement is taken with the wing bent at a 90-degree angle, from the most prominent point of the wrist joint to the most prominent point of the longest primary feather. It is often taken as a standard measurement of the proportions of a bird and used to differentiate between species and subspecies. See also * Bird measurement Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The measurements of the lengths of specific parts and the weights of birds varies between species, populations within species, between the sex ... References {{Bird-stub Bird anatomy ...
